EYEGLASS-MOUN TING.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed December 14, 1916. Serial No. 137,019.

I '0 all whom it may concern:

Be it known that I, JosEPI-I RosnNBLA'rT, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Eyeglass-Mountings, of which the following is a specification.

This invention relates to improvements in lens mountings more particularly to the frameless type used in eyeglasses and spectacles, and the object of this invention is to provide such a mounting with one or more attaching ears, and a saddle portion having two oppositely extending arms against which the edge of the lens rests, one of said arms being substantially rigid or non-yieldable, while the other is formed resilient and springy for the purpose of engaging the edge of the lens with a yielding pressure, to hold its axes uniformly in correct position.

It is found in practice in many instances undesirable to bind the lens tightly between the lens clamping ears in order to hold them rigidly therein and maintain their axes in the correct relative position, as such a bind ing effect often causes the lens to crack owing to uneven expansion and contraction due to varying temperatures.

To obviate this difiiculty, I have provided means whereby the lens may be held loosely in the ears, and have provided a two arm saddle against which the edge of the lens may rest, the upper arm serving as a correct stop or guide while the lower arm is formed resilient or springy and reaches around beneath or below the horizontal axis of the lens and presses its edge upward with a yielding pressure against its stopping arm. By my improved construction, it will be seen that the lens may be loosely held to yield in its clip or mounting and yet be accurately returned to its normal position even when forced out in the handling.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims;

In the accompanying drawings:

Figure 1 is a side elevation of a portion of an eyeglass mounting engaging the edge of the lens.

Fig. 2 is a perspective view of the clip portion of the mounting engaging the lens.

Fig. 3- is an edge view showing a mountmg with but one lens securing ear.

Fig. t is a modification showing the free end of the non-yielding arm of the saddle, as folded over upon itself.

Referring to the drawings, 10 designates the nose bridge member of the mounting, a

portion of which is shown herein, which bridge serves to connect together the opposite. lenses 11. To the end of this bridge is shown as being secured the usual lug 12 when the same is used for a finger piece mounting, but which lug, of course, is not necessary when the mounting is used on a spectacle type of frame.

The lens 11 is held in position between a pair of clamping ears 13 by means of a screw 14 through their free ends. The inner ends of the ears are connected to the saddle portion 15.

My invention lies essentially in the special construction of this saddle portion which is provided with two oppositely extending arms 16 and 17. The arm 16 extends upwardly and is comparatively thick and heavy and is non-yielding or non-bendable for the reason that this arm serves as a positive stop or gage against which the edge 18 of the lens rests. The lower arm 17 is essentially of a resilient or springy character and may be so formed by any suitable method of construction. This arm is preferably of a length greater than that of the arm 16 and is formed nicely tapering and extends around beneath the edge 19 of the lens engaging the same with a yielding pressure, that is the spring arm would naturally set inward as illustrated by the dotted lines in Fig. 1 when released or before the lens is mounted in the clip.

The exerting of this spring tension against the edge of the lens serves to hold the lens up in its proper position with its upper edge 18 resting against the stop arm 16, whereby the natural dropping tendency of the lens due to gravity is overcome and the axis of the lens is maintained in its proper position.

In some instances instead of forming two opposite ears for engaging opposite sides of the lens, I simply use one ear as illustrated in Fig. 3, whereby the mounting will accommodate lenses of different thicknesses.

The modification shown in Fig. 4: simply illustrates a construction whereby the free end of the upper arm may be folded over against itself for the purpose of thickening up this end if desired.

In the foregoing description and in the accompanying drawings, I have described and illustrated what I have found to be the preferable form of the spring saddle best adapted to the accomplishment of the desired ends, but it is possible that in the utili zation of such a device in connection with other forms of lenses than that which I have illustrated, various changes in shape and form of the several features of the device may be necessary. I, therefore, desire it to be understood that I reserve the privilege of resorting to all such various mechanical changes to which the device is clearly susceptible within the spirit and scope of the appended claims.

I claim:

1. A lens mounting comprising a clip having means by which it is attached to the lens,

a saddle portion on the clip having oppositely extending arms for-engaging the edges of the lens both being formed of a single piece of metal, one of said arms beingrela .tively rigid to form a stop and the other of a length greater than that of the rigid arm and a1 'anged to engage the edge of the lens with a yielding pressure.

In testimony whereof I afiix my signature in presence of a witness.
